WATER-NOZZLE.

SPECIFICATION forming part of Letters Patent No. 617,472, dated January 10, 1899.

Application filed August 17, 1897.

To all whom it may concern.-

Be it known that we, HORACE FALK NEU- MEYER, residing at Macungie, in the county of Lehigh and State of Pennsylvania, and JONAS FRANCIS YOUNG, residing at Niagara Falls, in the county of Niagara and State of New York, citizens of the United States, have invented a new and useful Water-Nozzle, of whichthe following is a specification.

This invention relates to Water-nozzles; and it has for its object to provide a new and useful nozzle of this character well adapted for fire and domestic purposes.

Vith this end in View the present invention contemplates a simple and efficient construction of water-nozzle having provision for throwing either a solid stream or spray and for regulating the density of the spray as may be desired and inthe accomplishment of these objects to provide a construction having an entire absence. of parts that are capable of getting out of order.

With these and other objects in View, which will readily appear as the nature of the invention is better understood, the same con sists in the novel construction, combination, and arrangement of parts hereinafter more fully described, illustrated, and claimed.

Referring to the drawings, Figure 1 is a perspective View of a water-nozzle constructed in accordance with this invention. Fig. 2 is a similar View with the outer rotatable tube and spraying-plate removed. Fig. 3 is a central longitudinal sectional view of the complete nozzle. Fig. 4 is an end View thereof. Fig. 5 is a cross-sectional View on the line 5 5 of Fig. 3. Fig. 6 is a detail in perspective of the hinged spraying-plate.

Referring to the accompanying drawings, the numeral 1 designates the nozzle-body, provided at one end with the usual interiorlythreaded coupling socket or cup 2, adapted to be coupled to the hosein connection with which the nozzle is employed, and beyond the coupling socket or cup 2 the nozzle-body is extended into an inner discharge-tube 3, having an inner tapered-bore portion at and a straight-bore portion 5, extending from the the small end of the tapered bore 4 to the extreme outer end of the discharge-tube.

Serial No. 6&8,5S2. (No model.)

and the orifice at the discharging end of said tube 3 is intersected by a flat or curved inclined valve-seat 7, formed on one side of the tube 3 and designed to form a seat for the hinged spraying plate or valve 8, working on. the discharge-tube directly over the said inclined valve-seat 7.

The spraying or valve plate 8 is provided with a fiat or curved surface 9, opposing the seat 7, and which flat or curved surface is also designed to extend over the orifice at the outer end of the tube 3, so as to receive the impact of water thereagainst and provide for breaking the stream into a spray, as will be hereinafter more fully explained. said spraying-plate 8 is of a sufficient length so as to extend slightly beyond the plane of the outer end of the tube 3 and is provided at its inner end with a T-head, 10 loosely engaging in a correspondinglysgiaped.bearingsocket 11, formed in one si t of the wide bearing-collar 12, which is formed on'the exterior of the nozzle-body 1 intermediate. the ends of the latter. The T-head 10 and T- socket 11 form a loose hinge-bearing for one end of the spraying-plate 8, and said plate is further provided between its ends with a transversely-disposed convex bearing-rib 13, the inner side of which is formed with a kerf 14 to receive one end of a short leaf-spring 15, the other end of which spring is adapted to register in a shallow seat 16, formed in the collar 12 directly at one side of the T bearingsocket 11. The end of the spring 15 opposite its connection with the spraying-plate 8 is held within its seat 16 by means of the outer rotatable adjusting-tube 17, which tube is of a cylindrical form throughout and has the inner end portion thereof snugly fit'and turn on the wide bearing-collar 12 of the nozzle-- body. Then the tube 17 is in the position specified, the same not only holds one end of the spring 15 fast, but forms a housing for the spraying-plate S and permits said plate to be The normally held awayfrom the seat '7 by means of the tension of the spring.

The outer rotatable adjusting-tube 17 is retained in a working position 011 the nozzlebody by means of a retaining screw-pin 18, fitted in one side thereof near its inner end and working in the annular guide-groove 19, formed in the bearing-collar 12, said pin-andgroove connection preventing the displacement of the outer tube, while at the same time permitting of the necessary rotation thereof to effect an adjustment of the spraying-plate S. The said outer rotatable adjusting-tube 17 is provided at a point intermediate of its ends with an interior annular groove 18, normally receiving therein the convex bearingrib 13 of the plate 8, so as to permit the latter to normally lie close against the inner side of the tube 17 when a solid stream of water is being thrown from the nozzle, and within the plane of the tube 13 the tube 17 is further provided at the inner side thereof with a circularly-arranged inwardly-projecting cam-lug 19", adapted to be carried in and out of contact with the rib 13 of the plate, as clearly illustrated in the drawings.

To provide for a positive movement of the spraying-plate8 toward and away from the seat 7, there is employed a ring guide-yoke 20, which registers inside of the outer tube 17 and embraces the outer end portion of the discharge-tube 3. The ring guide-yoke 20 is secured fast by means of the screws 21 or other suitable detachable connection to a securingflange 22, formed on the tube 3 and projected from the side thereof opposite the inclined valve-seat 7 and said guide-yoke 20 is formed in the side next to the plate 8 with a guideopening 23, within which the plate 8 works, and is thereby prevented from undue lateral play or movement during adjustment. This construction insures all parts of the nozzle being maintained in a proper working relation.

In the normal position of the different parts of the nozzle the spraying-plate S will be held away from the seat 7, thereby permitting a solid stream to issue from the tube 3 5 but when it is desired to contract the stream and to reduce the same into a spray or sheet the outer rotatable tube 17 is turned so as to carry the cam-lug 19 against the rib 13 of the plate 8, thereby moving said plate inwardly toward the seat 7, and the nearer the plate 8 is adjusted toward said seat the greater will be the density or fineness of the spray, and at this point it is to be observed that the lat eral channels 6 at the outer end of the tube 3 permit of a widening of the sheet of water as it is deflected from the plate 8, as the latter is adjusted in close proximity to or directly on the seat 7.

From the foregoing it is thought that the construction, operation, and the many advantages of the herein-described water-nozzle will be readily apparent to those skilled in the art without further description ,and it will ing-plate arranged between the two tubes,

and means, carried by the outer tube, for forcing said spraying-plate to a position over said inclined surface of the inner tube, and for holding the same rigid in its adjusted position, substantially as set forth.
